INTRODUCTION
INTRODUCTION/BACKGROUND
Use short duration waveforms: processed purely in the time domain, not in frequency domain
Simple concept: only a few components in TX and RX
Simple digital processing Low complexity Low cost
No components for processing frequency information except LNA and wideband tuning (e.g. filter, osc., etc.)
Excellent co-existence capability due to adaptive frequency band use – flexible to eliminate forbidden bands (e.g. active incumbent TV user bands, active microphone bands, etc.)
Dynamically frequency bands can be assigned to CPEs
New waveforms have steep out-of-band rejection around the edges of the band.
